Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042372, here are decompositions:

  • 3 + 1042369 = 1042372
  • 41 + 1042331 = 1042372
  • 101 + 1042271 = 1042372
  • 113 + 1042259 = 1042372
  • 131 + 1042241 = 1042372
  • 179 + 1042193 = 1042372
  • 239 + 1042133 = 1042372
  • 251 + 1042121 = 1042372

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 4, 2372 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2372-04-01 (DMMYYYY (Euro, single-digit day))
  • 2372-10-04 (MMDYYYY (US, single-digit day))
  • 2372-04-10 (DDMYYYY (Euro, single-digit month))
Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,042,372 and was likely granted around 1912.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 1042372 first appears in π at position 482,457 of the decimal expansion (the 482,457ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
